specification of Letters Patent. Patented Apr, 27, 1915 Application filed May 8, 1914. Serial N 0. 837,320.

To all whom it may) concern Be it known that I, OSCAR H. NEIMAN, a

citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certaln new and useful Improvements in Lubricators;

and I do hereby declare thefollowing to be a full, clear, and exact description of the mvention, such as will enable others skilled 7 means may be used for forcing out the luin the art to which it appertains to make and use the same.

This invention relates to force feed lubri-f cators for grease, of the kind shown in the Patent No. 984,839, issued to me on February 21, 1911; and it consists in certain im provements to the removable cover and outlet pipe as hereinafter fully described and claimed. i

In the drawings, Figure 1 is a side view of a lubricator constructed according to this invention, showing its lower portion in sec tion. Fig. 2 is a plan view, from below, with the cover removed. Fig. 3 is a plan view of the cover, from above. 7

The body portion 2 of the lubricator is a cylinder for holding grease or other similar lubricating material, and it has a piston 3 which is slidable vertically in it. The piston is forced downwardly by means of a handwheel 4 and a piston-rod 5, the construction of these parts being preferably as shown in the aforesaid patent, but any other approved bricant from the cylinder.

The bottom end portion of the cylinder has two inwardly projecting lugs or pins 6, and 7 is a bridge-piece or crossbar the end portions of which are slipped into engagement with the said lugs. The outlet pipe 8 for the grease is secured to the middle part of the bridge-piece, and it has a screwthreaded portion 9.

The cover 10 is conical in form, and it has a central hole 12 through which the outlet pipe is arranged toproject. The periphery of the cover has a groove 14:, or other approved means, for making a grease-tight joint with the bottom end of the cylinder.

A nut 15, which is preferably a wing-nut or thumb-nut, is screwed on the projecting screwthreaded portion of the pipe 8, and it secures the cover in place, a packing washer 16 being interposed between the nut and the cover. I

The crossbar or bridge-piecehasribs 17 on it which bear on the lugs 6 and prevent it from revolving in one direction, and the cover has a forked guide jaw 18 which projects upwardly and engages with one of the ribs 17. A helical spring 20 is arranged around the outlet pipe between the cover and the middle portion of the bridge-piece, so

:that the cover and crossbar are held relatively in place by spring pressure before the nut is tightened. This spring also releases the bridge-piece or crossbar from the lugs when the nut is unscrewed. The guide jaw 18 enables the crossbar or bridge-piece to be arranged in engagement with the lugs, by placingrit in the cylinder and moving the cover circumferentially until the engagement. is efl'ected. The spring 20 holds the crossbar at a suitable distance away from the cover, before the nut is screwed up, so that the end portions of the crossbar may be slipped behind or under the pins 6. The tighening of the nut then forces the groove ofthe cover over the bottom end. of the cylinder, and completes the engagement of the crossbar with the pins.

The cover can be removed and replaced with facility as often as required to fill the cylinder with grease, and the construction of the parts is such as to form a veryefiective closure for the outlet end of the lubricator. V

What I claim is:

1. In a lubricator, the combination, with a cylinder provided with projections at its lower end portion, and means for ejecting the lubricating material from the cylinder;

of a crossbar whichengages with the saidprojections and which has an outlet pipe at its middle part, a cover closing the outlet end of the cylinder and having a hole for the outlet pipe to project through, and means for securing the cover on the outlet pipe.

2. In a lubricator, the combination, with a cylinder provided with projections at its lower end portion, and means for ejecting the lubricating material from the cylinder; of a crossbar which engages with the said projections and which has an outlet pipe at its middle part, a cover closing the outlet end of the cylinder and having a hole for the outlet pipe to project through, a helical spring encirclingthe outlet pipe and arranged between the cover and the crossbar, and means for securing the cover on the outlet pipe.

3. In a lubricator, the combination, with a cylinder provided with projections at its lower end portion, and means for ejecting gaging slidably with the crossbar,' and means the lubricating material from the cylinder; for securing the cover on the outlet pipe. 10
